The S-OPT optical connectors are Neutrik® OpticalCon® connectors and support Mobile Fiber Cable from Neutrik®. This optical interface provides for transmitting audio over long distances via optical while still taking advantage of the RSS Digital Snake System’s mobility. OpticalCon® provides a Dual LC optical connector (standard LC-Duplex connector, IEC 61754-20) enabling the use of less expensive optical cables for with the Roland Digital Snake System.Two S-OPT units can be connected using the proprietary POWER LINK cable (ARC-15, sold separately) so that redundant power can be supplied from one unit to the other. If power to a single unit is interrupted due to some situation or is damaged, both units will still continue to operate.
